In your opinion, is it ok for a baby to be vegan from weaning (6 months)?

Veganism is an ethical philosophy not a diet. It’s about not exploiting or harming animals.

if a mother is feeding her baby with her own breast milk who is she exploiting?

It’s actually about avoiding the use of all animal derived products.

I think it’s unfair to restrict your child’s diet based on your own belief system.
My kids are allowed to try all food.
They can then make their own, informed, choices as adults.

I know this seems to infuriate some vegans/ religious people. But I guess it’s on brand for them to demand we all think the same way as them 🤷🏻‍♀️

It's also unfair for someone whose belief system means they don't eat animals or animal milk to have to buy and prepare those things.

I say this as a meat and dairy eater.

We all eat too much meat. Exposing a child to a wide range of vegetables and alternative proteins from birth will set them up for a healthy life. If they choose to add meat or dairy to it later, fine.

I don't think it's unfair to raise any child according to your beliefs - it's your job to instil decent values in your child. As long as you're willing to accept that when they know their own mind better, they might eat the meat or abandon the church - all good.

If you're vegan and you're planning for your baby to be vegan, too, then your baby is in imminent danger of B12, vitamin D and iron shortage. At the very minimum I would ask for a dietician appointment with the GP to discuss this with a trained and registered professional, not using an online forum for a potentially health problem inducing situation for your baby. And FYI, human milk is not vegan.

What on earth? 🤭

QuaintGreenFawn · 02/02/2026 08:21

To answer OP's question - yes it is possible, especially at home you can obviously feed your child whatever you want. It will be hard to have nutritionally balanced meals, with all their protein / iron / calcium needs if they go through fussy phases.
It will be harder outside of the home (unless your friends are also vegan) - they are likely to miss out on things at parties and playdates, or will be offered UPF alternatives. Nurseries and school in my experience are not great at nutritionally balanced vegan meals. Vegetarian outside the home will be easier.

Yeah I get that but she said her milk is dairy free because she's vegan, I'm just pointing out that her milk is dairy just like the vegan cows milk is dairy 😀

vegan isn’t really a diet composition thing, it’s a philosophy of not exploiting animals. So your own human milk willingly given is fine.

SunSparkle · 02/02/2026 08:26

Gosh I didn’t even think of nursery when I made my previous comment. The vegetarian options at some nurseries are absolutely dire either completely just using quorn/processed meat replacements or seeming totally inadequate for the amount of calories they need so choose a placement carefully or one where you can provide your own meals (though most won’t warm food up).

the difference between an adult vegan diet and that for a child is that the child needs loads more fat and protein for the sheer amount of growth and carbs for daily energy. A diet of fruit and veg and grains etc need a hefty amount of oil, coconut cream, nut butters, avocado etc for it to be calorie dense enough.

There’s guidance on which alternative milks to use because almond milk is too low in fat and calories and therefore oat milk is normally recommended as it’s higher fat and calories (by virtue of added oil).

letting baby eat what you eat may not be sufficiently calorie dense for them particularly when they only eat such small portions.

That's only true for ethical vegans, though. Some people are vegan for health reasons, and the ethics don't really come into it so much.

The actual definition of veganism is "abstaining from the use of animal products and the consumption of animal source foods" - the philosophy is optional.

OtterlyAstounding · 02/02/2026 08:15

I mean, it might be ethically vegan, but in terms of 'not consuming animal products' it fails at the first hurdle. On a very literal level, drinking breast milk is consuming an animal product (dairy), so it's not 'abstaining from the use of animal products and the consumption of animal source foods'.

I don't think anyone is going to get angry at babies for breaking their vegan diet in order to include a little ethical breast milk, though!

Veganism is a belief system not a diet. 'Vegan diet' is just a quick way of saying 'eat in a way that aligns with the ethics of veganism' so not exploiting animals.
So actually in your earlier example of road kill, I would argue that that is within the ethics of veganism.
I say that 'I'm vegan' but really I mean I eat no meat fish eggs or dairy. I do this because I believe its healthier. The ethical side is bonus, but i cant say i dont exploit animals in other ways (i have pet cats, ive ridden a horse). So arguably your road kill eating uncle could be more vegan than me.

Are all vegans vegans for ethical reasons? I didn’t think so.

SparklyGlitterballs · 02/02/2026 08:32

I think the takeaway here is to consult a paediatric nutritionist to ensure you do it correctly OP. Raising a child vegan from birth is completely different from going vegan as an adult, as you have to ensure you provide all the necessary nutrients a developing body and brain needs, and what foods to avoid (eg soya milk). You also have to be prepared to adapt if your baby has intolerances or is fussy with food.

rockinrobins · 02/02/2026 08:32

I think it's entirely possible but you would have to learn a lot about nutrition and really be careful to make sure baby is getting everything they need.

It would need more effort and planning in terms of food prep etc.

Babies need a higher proportion of some nutrients than adults as they are growing so much. Their bodies can't cope as well as an adult body with a vegan diet.

So yes you can do it but you do need to do some research first.

Poetnojo · 02/02/2026 00:07

But it's still mammalian milk.
Cows are vegan so is their milk also vegan by that logic

Good point

IpsyUpsyDaisyDoos · 02/02/2026 08:34

ShawnaMacallister · 02/02/2026 07:50

No. Vegans carefully plan to ensure they consume enough protein and essential vitamins and amino acids. There are a small minority who eat UPF shit and carbs but most vegans know what they need to eat to be in optimum health.

Does that extend to what a baby needs to eat though?

I know what I need to eat but that's different to what a child needs. So the careful planning of meals doubles.

My child is 6 months old, it quite literally is entirely up to me to choose what they eat. I’m vegan, therefore I’m not going to buy and prepare meat and dairy products am I, defeats the whole point of being vegan because I’d still be supporting those industries with my money

Why on earth did you ask then? You’re very sure you’re making the right decision. Not saying I disagree with that decision, but I don’t understand why posters start threads asking if they’re being unreasonable, then declare very stridently that they definitely aren’t. What a waste of time. Surely you must have avocado to mash?

Thedevilhasfinallycaughtupwithhim · 02/02/2026 08:35

5128gap · 02/02/2026 08:16

Funny, how its the non vegans who appear to be trying to impose their beliefs on a vegan on this thread then, isn't it? No one who isn't vegan or an expert in child nutrition can have anything useful to say in response to this OP. Yet once again, the word 'vegan' in a thread title has people for whom veganism has nothing to do with their lives rushing over to comment. Is that not just another way to "demand people think the same as them"?

Is this a direct reply to me or are you just generally mad that people disagree with you?

Glitterella · 02/02/2026 08:37

Strangerthanfictions · 02/02/2026 08:33

Good point

My logic on this says no because vegans choose not to eat animal products (for ethical or just as a choice) which would include cows milk. Therefore cows milk is not vegan and humans milk is vegan (because that is what we are meant to do) ie nurse our young.

That's not true though? From what I've read, veganism is literally just 'abstaining from the use of animal products and the consumption of animal source foods'. Sometimes it's done for health, and sometimes for ethical reasons.

It's interesting to know though, that ethical veganism isn't actually against the consumption or use of animal products.

Irren · 02/02/2026 08:37

Of course human milk is vegan, the human is willingly giving it. @ChangePrivacyQuestion you are right that supplementation is needed, and utterly wrong about that.
OP, I have a very healthy vegan from birth ten year old and three year old, both tall, sturdy smart lads. This is a very useful document designed for childcare settings in UK. https://www.justonenorfolk.nhs.uk/media/ocagvmhe/eating-well-vegans-web-compressed.pdf

And how does the cow consent to its milk being given to a baby not its own, just out of interest?

No, that's plant-based. Veganism is an ethical system of minimal harm.

Human milk is vegan because it is not an animal product. Ie of another animal! Mammals feed their young via lactation.

Consuming the product of another animal is not vegan. Consuming the product of your own lactating mother is vegan ie as nature intended.

Irren · 02/02/2026 08:41

I don't think it's fair.

Firstly we don't know enough about vegan diets and long term or paediatric health. Humo Sapien is not a herbivores, our species evolved to eat some animal protein, so logical to assume that those foods play an important part in our diet.
There are many substances in non plant food that are only found there. I have a coiuple of vegan friends, both have to take supplements - one is permanently anemic, the other has to have monthly vitamin B12 injections.
Why would you gamble with your baby's long term health and current development?

I also think we don't have the right to choose veganism on behalf of a child. People are vegans for many reasons, and absolutely have the right to choose. The child should have the right to make that choice too- once they are old enough to understand.

I don't think you should choose animal abuse and killing on behalf of your child but each to their own. All you're really saying is that you are making a more conventional choice.
Supplementation is extremely easy. Veg 1 from vegan society. fortified soy milk provides about the same calcium as dairy milk (other milks less so.) Keep a careful eye on iron as all parents should.

I don’t think it’s nutritionally ideal

I’m in “they can make their own decisions when old enough ” camp.

DS announced he wanted to be vegetarian aged 5 and he’s been supported in that choice.
